The screen would be 128.80" wide x 64.40" high. Eyes to screen in the front row would be 12'. That would kind of cover a lot of aspects maybe. I may need to look into that as well.
Keep in mind this line running thru this thread was originated by
in post 296 when he asked what size screen would work for him in his room.
Because this thread is the only place on AVS it is truly safe to talk about variable AR presentation I nicknamed PIA we get many a thread within a thread when someone posts here. Or I have a chain of PMs with someone that then doesn’t benefit the community at large.
So it is his screen size and AR we are talking about here.
As to 2.0:1 AR screens go. I know there are more than a few members here that had hoped that the TV standard when it changed from 4:3 to 16:9 had instead made it 2.0:1 That as an AR would have been fine with me as well. But it didn’t it is 16:9 and unless someone persuade the world to once again spend billions switching to something new it will stay 16:9 1.77:1 IMO. It is the shape of TV it is the field of most projectors and it is the container media is formatted to. IMAX is 1.89 in theaters but much of it when extracted to home media is being done as 16:9. That’s up to the filmmakers if we get thin black bars or not, but the package is 1.77:1.
With my screen being a stealth wall of nondescript size and AR, I guess I could go thru all my antics of viewing and zooming for a year and marking all the widths and heights I use and come up with a screen AR and size that would include all. I know if I watched Dunkirk or Aquaman once the frame would be 1.77, but if I watched The Hateful Eight 2.76:1 just once it might be closer to 2.0:1 as I like to view that movie the same height I view most scope movies for no other reason than because I can.
So ya I guess I can see using any screen AR you want as long as it will hold everything you want to watch at the size you like to watch it. That statement even holds true for the guys here that have and love a 2.35:1 screen because I have been told many times Dunkirk or Aquaman look perfect fit into their screens.
So if more people didn’t mount their projector at a fixed distance at first and used a painted wall much larger than needed as a test screen for a while and for 6 months or so just played with sizes without moving their seats they to could come up with a custom AR to suit their needs. For simplicity I suggest a 16:9 screen if space permits sized to IMAX and then hopefully most everything else will fit in.
